Origin of pulmonary artery branch from ascending aorta. Primary surgical repair in infancy

Origin of a pulmonary artery branch from the ascending aorta is a rare congenital anomaly and has been associated with a high surgical mortality. We are reporting three cases in which repair was facilitated by the use of deep hypothermic circulatory arrest in infants from 2 to 8 weeks of age. In addition, we hope to clarify the spectrum of anomalies which have been included incorrectly under this terminology and are reproposing an embryologic theory.
